Summary

The aim of this clinical study is to evaluate the efficacy and dental sensitivity associated with Combined Bleaching Technique (in-office + at-home) varying in-office bleaching application under two different time protocols, and dentifrice containing arginine 8% and carbonate calcium use. One hundred eight participants who meet the study inclusion criteria will be selected. The desensitizing agent used will be a dentifrice containing 8% arginine and calcium carbonate. In each evaluation will be determined: tooth sensitivity and color. The data collected will be submitted to the factorial statistical analysis for evaluation of color and chi-square test for tooth sensitivity (α = 5%).
